[QUOTE=R.D. Silverman;408702]Yes, I know quite a few of them. However, just to cite one ambiguity, skew can be either c_0/c_max or c_max/c_0.
lambda could be a tolerance limit (as an exponent) for the size of the cofactor, (i.e. accept max_prime^lambda)
lpbr is clear, but mpbr is not.[/QUOTE]The latter is used to indicate the maximum size of composite cofactors in bits, just as lpbr is the maximum size for prime cofactors. mfp(a/r) is typically 1.5-2.0 * lpbr

Silverman, did you send the data file to Paul? I already gave instructions to my sieve machines to start sieving for the 14e application.

GW_5_345
 
I'll take [B]GW_5_345[/B] into LA once it is done sieving. Thanks.

I'll take GW_10_240 and C179_139_61 once sieving is compete. Thanks.

Sort of about three days on i7/4930K with -t 6, target density 120.

Log attached; don't believe the linear-algebra elapsed time, I paused the job to run another one in the middle.
